Petralon Energy is an African exploration and production company with proven capacity to acquire, develop, finance, and operate oil and gas assets.
Operating through its subsidiary Petralon 54, the company holds a 100% working interest in the Dawes Island Field in the Eastern Niger Delta.
In just under six months, Petralon 54 has revamped its production capacity significantly through its recently established DI-3 well. Operations began on 14 March 2026 and has since delivered average additional daily production of approximately 2,800 barrels of oil per day (bopd), bringing the field's combined production capacity to approximately 4,800 bopd.
DI-2 has been onstream since October 2025 and DI-3 builds directly on the performance of its predecessor. Together, the two wells have sustained back-to-back drilling programme on a field that was non-producing at the time of Petralon's acquisition in 2021. Till date, the company has exported over 350,000 barrels of oil from the field via the Bonny Oil and Gas Terminal, which is located around 30km from the field. The DI-3 well became operational with zero lost-time incidents and it reflects the company's commitment to world-class health, safety, and environmental standards across its operations.
Dawes Island is located approximately 15km from Port Harcourt in the Eastern Niger Delta. The island covers roughly 46 sq km and holds an estimated 17.6 mn barrels of recoverable oil. “Our success at Dawes Island was built on the conviction that Nigerians could acquire, develop, and operate world-class energy assets. That conviction once required courage, today, it stands on proof. The easy thing after DI-2 would have been to pause, but the determination and resilience of every single member of the Petralon team drove us forward, and DI-3 is the result of that effort. Progress like this is only possible through the strong collaboration we have built with our host communities, our regulator, and our partners. This is only the beginning of what Dawes Island can deliver," said Ahonsi Unuigbe, founder and chief executive officer of Petralon Energy.
Through the commencement of DI-3 production, Petralon Energy validates another major step in the phased development of Dawes Island. The company stays focused on growing production, strengthening its position as a leading indigenous operator in Nigeria's upstream sector, and advancing its longer-term ambition for the field.

Saipem and Petrobras have signed an agreement to initiate a technical dialogue aimed at assessing and potentially developing integrated solutions for decommissioning activities in Brazil, relating to oil and gas fields, subsea systems and associated infrastructure.
The one-year agreement focuses on plug and abandonment activities as well as subsea decommissioning, and defines a framework for technical and operational collaboration between the two companies, with the aim of improving the efficiency, sustainability and level of innovation of end of life infrastructure activities.
Under the agreement, Saipem and Petrobras will collaborate in the assessment of potential partnerships with specialised companies and institutions for decommissioning activities, as well as in the development and implementation of new technologies, methodologies and integrated solutions for this specific type of activity.
The cooperation will also include the evaluation of logistical and operational alternatives, such as the use of drilling units and vessels, as well as the enhancement of existing practices to address the main technical and operational challenges related to decommissioning activities.
Brazil is one of the world’s largest decommissioning markets. Since 2013, Petrobras has decommissioned the fixed Cação platforms (PCA-1, PCA-2 and PCA-3), in the Espírito Santo Basin, its own floating platforms P-7, P-12, P-15, P-27, P-34, in the Campos Basin, in addition to the chartered floating platforms FPSO Piranema Spirit, in the Sergipe Alagoas Basin, FPSO Brasil, FPSO Marlim Sul, FPSO Rio de Janeiro, FPSO Rio das Ostras, in the Campos Basin and FPSO Cidade de São Vicente, in the Santos Basin. 23 platforms and 2,000km flexible lines are set to be decommissioned by 2028, with a further 40 platforms after 2028.
Petrobras stresses the opportunities arising from decommissioning, and the potential to develop a new production chain, generating employment, income and value for society. It also emphasises the sustainable decommissioning model, with a circular economy approach and respect for the environment and local populations, as well as its focus on R&D into new decommissioning technologies and approaches.
Saipem meanwhkle has completed over 30 major decommissioning projects in various countries in the world since 1995. Its integrated engineering capabilities, logistics expertise and strong partnerships have enabled the company to successfully complete projects of any size in a wide variety of contexts.
Following preliminary estimates from drilling activities offshore Eastern Mediterranean, Eni is anticipating the presence of approximately 2 trillion cubic feet of gas initially in place and 130 Mbbl of associated condensates.
Discovered from the Denise W 1 exploration well, it especially aligns with the major's near-field and infrastructure-led exploration strategy as it comes with the potential for a massive fast-track development. The well is positioned less than 10 kms away from existing infrastructure, belonging to the Temsah Concession lying 70 km offshore in 95 m of water depth.
As part of substantial investments in brownfield assets, Eni had secured a 20-year renewal of the Temsah Concession in 2025 from the Egyptian General Petroleum Corporation and Egyptian Natural Gas Holding Company. The discovery thus comes as a significant return of investment for the oil major, similar to the now-producing Temsah field, which also featured a gas-bearing sandstone reservoir of excellent quality with about 50 m of net pay like the Denise well.
Eni's joint venture with EGPC, Petrobel, which operates the Denise Development Lease of the Temsah Concession, secures boosted gas output for the country, contributing to its national goals and energy security.
Eni operates the Denise Development Lease of the Temsah Concession with a 50% contractor working interest, alongside bp which holds the remaining 50%.
Eni has been active in Egypt since 1954 and today holds a diversified portfolio spanning exploration, development, and production, with oil and gas production of 242 kboed equity in 2025.

Malaysia is entering a significant phase of offshore decommissioning as numerous ageing oil and gas platforms in the South China Sea reach the end of their operational lives.
PETRONAS is leading the effort to safely retire these installations through a combination of full removals, well plug and abandonment (P&A) operations, and selective repurposing.
As of May 2026, PETRONAS Carigali is progressing a major tender for the removal of up to 31 offshore platforms.
The tender, which covers structures ranging from approximately 100 tonnes to 15,000 tonnes, is expected to be awarded in packages across Sarawak, Sabah, and Peninsular Malaysia.
Industry contractors have shown strong interest in the work, which forms part of a broader programme to address ageing infrastructure.
Well abandonment activities are also advancing.
In early 2026, T7 Global Berhad, through its subsidiary Tanjung Offshore Services, completed well abandonment operations at the Zuhal East field.
Separately, HELMS Geomarine carried out geotechnical drilling campaigns in Sarawak waters between late January and late March 2026 to support jack-up rig operations for future P&A work.
PETRONAS has a track record in rigs-to-reefs (R2R) projects.
Since 2004, five offshore platforms have been successfully converted into artificial reefs, including Baram-8 in Sarawak and structures offshore Terengganu.
These projects aim to support marine biodiversity while meeting environmental requirements.
However, current plans emphasise a case-by-case approach, with options for complete removal, partial decommissioning, or repurposing depending on technical, safety, and regulatory factors.
In its Activity Outlook 2026-2028, PETRONAS highlighted expanded well decommissioning and intervention programmes.
The company has established a Hydraulic Workover Unit (HWU) Academy to develop local expertise and position Malaysia as a regional centre for decommissioning services.
Discussions at OTC Asia 2026 in Kuala Lumpur focused on technology adoption, cost optimisation, and environmental compliance in offshore decommissioning.
Approximately 35 platforms in Malaysian waters are more than 40 years old, and industry estimates suggest substantial decommissioning expenditure over the coming decade.
All activities fall under the oversight of PETRONAS Malaysia Petroleum Management, which requires detailed decommissioning plans covering safety, structural integrity, and seabed restoration where full removal is selected.
The current wave of activity reflects maturing fields and the need to manage end-of-life assets responsibly.
While large-scale platform removals remain in the tender and planning stages, the pace of preparatory work and early contracts indicates that execution will increase in the coming years.
Malaysia's offshore decommissioning programme is expected to serve as a reference for other countries in Southeast Asia facing similar challenges with ageing infrastructure.
PETRONAS continues to stress the importance of balancing cost efficiency with environmental responsibility in all offshore abandonment projects.
Offshore group DOF has announced what it called a “substantial” contract award — valued at between US$25mn and US$50mn — for subsea commissioning support services in the Asia-Pacific (Apac) region.
The deal bolsters the group’s order book across the Apac region, according to Mons Aase, Chief Executive of DOF Group ASA.
Under the new contract, the company will deploy its Skandi Inventor vessel for the execution of the offshore operations, which are scheduled to commence in Q2 2027 in North Australian waters.
The Skandi Inventor is designed for subsea construction and remotely-operated vessel services in up to 3,000 metre water depths.
The scope of work includes DOF's in-house project management and engineering, procurement and logistics support services, with the offshore campaign estimated to blast between 120 and 180 days.
The announcement did not identify the client or the specific project that it will work on, but it reflects ongoing demand for offshore services across the Apac region in everything from subsea commissioning through to oil well interventions and decommissioning and abadnonment.
“The award recognises the capabilities of Skandi Inventor and DOF as a trusted partner in the APAC region,” said Aase.
“The award also secures strong backlog for the Apac region, and we look forward to continuing to deliver safe, efficient and world class subsea and marine services.”
Australia’s offshore regulator, Nopsema, has issued new guidance that clarifies requirements for offshore decommissioning in Commonwealth waters.
The guidelines seek to clarify regulatory requirements for the removal of offshore oil and gas assets and the sea dumping of infrastructure in Commonwealth waters as part of decommissioning.
These waters are ocean zones that typically begin 3 nautical miles (approximately 5.5 kilometres) off the Australian coast and extend outward to the edge of Australia's Exclusive Economic Zone (EEZ) at 200 nautical miles.
“Decommissioning is a normal and expected part of the lifecycle of every offshore oil and gas project,” a 15 May, 2026 Nosema statement read.
“Under Australian law, the full removal of offshore property and infrastructure is the default requirement once operations have ended. The new guidance provides clarity on how existing legislative frameworks apply to decommissioning activities, and how proposals are assessed where alternatives to full removal are put forward.”
The guidance explains how the Offshore Petroleum and Greenhouse Gas Storage Act 2006 and the Environment Protection (Sea Dumping) Act 1981 intersect when considering decommissioning outcomes.It outlines the categories of property and infrastructure that cannot be left in the marine environment, as well as those that may, in limited circumstances, be assessed by regulators to determine whether they are suitable to remain in the sea.
“The guidance aims to clarify application and assessment considerations for oil and gas titleholders or operators if proposing an alternative to full removal requirements to leave property or infrastructure in the sea,” the Nopsema statement added.
Importantly, it does not guarantee that any property or infrastructure will be approved to be left in place.
“Decisions are made on a case-by-case basis and must demonstrate that environmental and safety risks and impacts are acceptable under the relevant legislation. The guidance also supports early and proactive planning for decommissioning by setting out key application and assessment considerations for offshore titleholders and operators.”
The new guidelines were developed jointly by the Department of Industry, Science and Resources, the Department of Climate Change, Energy, the Environment and Water, alongside Nopsema, following public consultation in 2024.
It does not introduce new policy or regulatory requirements, but clarifies how existing requirements are applied in practice.The full guidance document is available via the Department of Industry, Science and Resources website.
TotalEnergies and the Egyptian Natural Gas Holding Company (EGAS) have signed a memorandum of understanding aimed at expanding cooperation on offshore exploration activities in Egypt’s north-western offshore region.
The agreement establishes a framework for technical collaboration covering early-stage exploration work and subsurface assessments across a large offshore area believed to hold promising deepwater hydrocarbon potential.
Under the partnership, both organisations will work jointly on geological and geophysical studies, technical evaluations and exploration-related activities designed to improve understanding of the region’s subsurface formations and identify future development opportunities.
The move reflects Egypt’s continued efforts to strengthen its position as a major energy hub in the Eastern Mediterranean while attracting further international investment into its offshore sector.
Nicola Mavilla, senior vice president exploration at TotalEnergies, said the agreement reinforces the company’s long-standing relationship with Egypt and supports future energy development efforts.
“We are pleased to launch this cooperation with EGAS, which reflects our shared ambition to further strengthen our partnership with Egypt,” he said.
“This agreement will support the assessment of Egypt’s deep offshore exploration potential and contribute to future energy development opportunities in the region.”
Egypt has become one of the region’s most active offshore energy markets in recent years, supported by significant gas discoveries and increased exploration activity from global energy companies. The country continues to invest heavily in expanding production capacity and strengthening energy infrastructure as demand for natural gas rises both domestically and internationally.
The new agreement is expected to support additional technical collaboration between TotalEnergies and EGAS while contributing to Egypt’s wider strategy of increasing offshore exploration and boosting long-term energy security.
EGAS plays a key role in managing Egypt’s natural gas resources and coordinating upstream activities with international operators. Through partnerships with foreign energy companies, the organisation aims to accelerate exploration programmes and encourage new investments across the sector.
TotalEnergies has continued to expand its footprint in Egypt through a range of exploration, production and energy development initiatives. The company views the Egyptian market as strategically important within its broader operations across North Africa and the Mediterranean region.
Industry analysts have noted that deepwater offshore exploration remains a priority area for many international operators due to the region’s untapped reserves and growing infrastructure network.
Alongside its oil and gas activities, TotalEnergies continues to pursue investments across renewable energy, electricity, biofuels and low-carbon energy solutions as part of its long-term transition strategy.
The company operates in around 120 countries and employs more than 100,000 people globally, with ongoing investments focused on balancing energy security, operational growth and lower-carbon energy development.
